SHOE-TREE-FORIVIING MACHINE. 7

Application filed August 3, 1922. Serial No. 579,518.

To all whom it may concern:

Be it known that I, OSCAR OLSON, a citizen of the United States, and resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Shoe- Tree-Forming Machine, of which the following is a full, clear, and exact description.

My invention relates to a shoe tree forming machine, and aims to provide a device of this character for the making of parts of shoe trees, although I wish it understood that the same may be employed for other purposes.

A primary object of the present invention is to provide a machine which will include a mechanism capable of handling any .desir able number of members to be formed (such as shoe trees) this handling or manipulating being accomplished in an extremely eficient and positive manner, the mechanism further embracing structure by means of which a single operator is enabled to control all parts of the machine, and to actuate the mechanism thereof to properly manipulate the articles being formed.

A second object of the invention is that of constructing a device of the character stated which may simultaneously form any desirable number of objects, such as parts of shoe trees, in the shortest interval of time, and by means of which wastage will be reduced to a minimum.

Vith these and numerous other objects in mind the present invention consists in the provision of a machine which in turn supports members such as blocks of Wood, whereby upon an operator following the out lineor guide provided by the model, the members will be correspondingly manipulated together with mechanism serving to operate upon these members to properly shape the same during this movement.

Reference is had to the attached sheets of drawings as illustrating one practical em machine embodying my improved construce tion.

Figure 12 is a fragmentary plan view of those parts of the mechanism which are essential to thesplitting of the articles, and showing the same in operation, and H Figure 18 is a side elevation of one of the finished articles which may be constructed by means of my machine.

Referring primarily to Figures 1, 2 and 3, it will be seen that in the embodiment illus trated, 1 show my machine as embracing a main frame 15, supporting apower shaft 16 in suitable bearings 17. The frame also carries, by means of brackets 18, a counter shaft 19, the ends of which I prefer to support in brackets 20, which latter are mounted for slidable movement within slots 21 formed in the frame 15, and extending longitudinally thereof, it being noted however, that movement of the brackets20 is normally prevented by means of bolts 22 which engage the frame for this purpose. Thus should an operator find it necessary to remove certain of'the devices hereinafter described, which are associated with the e 'nnits maybe aflixed tothe shaft 19, and'this ...Shaft further carries a suitable guide member 26' which is arrangedadjacentto an infdi'cating membersuch'as a pointer 27 carried-by the frame 15.

A secondary frame identified by the reference'numeral 28 is positioned adjacent to the shaft 19am issupported at this point "by meansofar'ms '29 rockingly carried by the shaft 30, 'andeach" supporting a counterbalance 81 atapoint beyond this shaft, the

upper ends of these arms providing beari'ng members 32 which support trunnions 33 afiiXed to the'frame 28. Thus it will be "obvjious;thatithdentire frame 28 maybe swung with" respect to the frame 15 by virtue of the support-provided by the arms 29, andit'will'be seent'hat'this frame may in turn be swungwithrespect to the arms 29 by virtue of the connection "established by the bearings 82, "and i the trunnions T-hus -the members carriedby the frame 28 may-'be"swung towards and away from the shaft 19 and also upwardly and downwardly with respect thereto for a purpose hereinafter brought out. 4o

"Also' as in Figures 1' to 3 it will'be'seen that a plurality of units are supported by the frame 28 i which correspond in number to the numberof-groups of cutting Wheels 24:, and saws'25 provided, and the detailed construction ofeach of these units is illustrated in Figures'Gand 7 in which it will be seen that the same comprises a drum rotatably mounted within a sleeve 35, which is in turn supported by the frame 28. The drum 3a 'is provided with a head 36, and th is' 'head' together with the head 37 associated with the oppositeend of the drum, serves to 'supp'ort a shaft 38 mounting cams 39. "Each of the heads is formed with an opening which maybe quadrangular, as hasl'been'shown, so that a block of wood 40, 'or'othersuitable member may be supported thereby, and by 'providing a handle ll in associationwith the shaft 38, the latterinay be turned subsequent to the insertion" of the member 40 to this position, so that the cams 39 carried thereby will engage the member to prevent any movement of the same with respect tothe drum.

'iAs" aforesta'ted, any desirable number 'of 44 0! other suitable element with one of these units, andmore particularly the head thereof, by "any suitable means such as bolts 45, it will be understood that an operator may revolve the drum, and the member carried thereby, by simply grasping the hand wheel and rotating thesame, which rotation will "be transmitted, by virtue of the engagement-of the bar 43 with the teeth 42,

to the heads of all of the units, thus revolving the latter "in'synchronism-t the one actuated by the operator.

Thus by associating a model-in the nature of a perfect member l6 With one of the units aforedescribed, it will be obvious that this modelmay be brought to a position adjacent the guide 26, it being of course understood, that, as in the'embodiment illustrated, the model receiving unituis positioned adjacent to this guide. Upon the "shaft, 19 now being rotated, an'operator may move the entire frame 28 in the manner hereinbefore set forth, to bring the members 40 and model 46 into engagement vwith the cutting wheels 24 and the guide 26. to thus shape the members 40 to conform t-o'the model. Also in addition to the con tact aforementioned, it will be understood that the model 46 and the members are rotated by the use of the hand wheel 44, and thus the'entire outer endsof the members 40 are cut to conform to the shape desired, this result being further accomplished by the use of the swinging action afforded by the trunnions 33 and the bearings 32. After the shaping operation has beenac- 'complished, an operator is at liberty to pull the'frame 28 rearwardlysoas to move the model 46 out of contact with the guide 26, and to correspondingly move the members 40 out of contact with the cutting wheels 24, it being understood that all of these operations are greatly facilitated by virtue of the counter-balance established by the weights 31.

During the operation aforedescribed, the parts will co-operate as in Figure s, and this co-operation will be continued until the ends of the each of the members 40 assume the shape shown in Figure12. In other words the ends of the members or wooden blocks -10 will beshaped to present two tree portions arranged with their lower faces abutting, and being integral with each other. Now with a view of separating these tree portions it will be noted that I provide the saws 25, and the shaft 30 may be moved from the full linepositionshown-in Figure 2 to that indicated in dotted lines by any suitable means such as a shaft bar 47 having a fork 48 co-operating with the collar 49 secured to the said shaft. Incident toth'e fact that the shaft supports the secondary frame 28 by means of the arm 29 it will be obvious that this shifting will result in a,

shifting of the frame. Thus the model 46 will be brought into alignment with the pointer 27 and an operator may now move the entire frame 28 towards the shaft 19. Incident to the fact that the parts are so disposed that when the pointer 27 is in line with the model, the central portion of the members 40 will be in line with the saws 25, it will be obvious that this movement of the frame will cause the saw to engage the outer shaped end of the members 40 to cut the same longitudinally as in Figure 12, thus accomplishing the second operation of the machine.

Now with a View of providing a mechanism which will serve to transversely cut the members 40, it will be seen that the frame 28 carries an extension 50 which in turn carries arms 51 providing a dovetailed track, as best shown in Figure 3. Slidab-ly mounted in this track is a'bar 52 which supports a plurality of guards corresponding in number to the number of units employed, and each of these guards preferably comprises, as in Figures 8, 9, l0, and 11 a frame 53 within which a saw 54 is disposed by means of a support 55, which latter in the embodiment illustrated mounts a roller 56 adjacent its lower face.

These saws may be reciprocated in any desirable manner, but in the embodiment illustrated it will be noted that I have shown an arm 57 v connected to the bar 52, and this arm is moved by a pitman 58 connected to a suitable source of power supply, such as a motor 59, carried by the extension 50. Thusit will be obvious that upon the motor 59 being actuated the arm 57 of the bar 52 will be reciprocated within the track provided in the arms 51, and incident to the fact that this bar rigidly supports the frame 53 carrying the saws 54, it will be obvious that the latter will be moved backward and forward along the track. To bring these saws to a position at which they will perform the cutting operation desired, I may utilize a lever 60, which is pivotally cariedby the extension 50 and the inner end of this lever is attached to a bracket 61 supporting tables 62 adjacent its ends. These tables underlie the split portion of the bar 52, and thus upon the same being projected upwardly by an a'ctuation'of the lever 60, it will be obvious that the saws 54 will also be moved i'lpwardly within their frames 53, incident to the engagement of the roller 56. with the tables 62 provided for this purpose.

Thusa third operation of the device consists in the operation of the mechanism in the manner aforedescribed which willcause the members 40 to be cut transversely so that finally the divided outer end of each of the members is cut transversely to provide two tree portions, one of which has been shown in Figure 13 and identified by the reference numeral63,

Summing up the operation of this device it will be understood that the same, although not necessarily limited to this particular use, is essentially a machine primarily intended for the manufacture of tree portions and similar articles, the. mechanism provided enabling a workman to simultaneously operate upon a number of tree portions. Thus any desired number of units are provided, and each of these units supports a block, and one of the same takes the form of a model positioned adjacent to suitable guide members such ashas been illustrated. The machine is now set in operation, and these members are engaged by the cutting, wheels 24 to shape the ends of the same, it being of course understood that previous to this actuation of the parts, the members are clamped into position by means of the locking mechanism shown. Incident to the great latitude of movement allowed these members, due to their mount.-

ing, the same will be quickly and accurately shaped to correspond to themodel, and the second operation of the mechanism, i. .e., that of bringing the shaped ends of the members into alignment with the saws 25, and the subsequent engagement of these parts, will cause the latter to penetrate the ends of the members to cut the same longitudinally,-as in Figure 12. The tree portions are now completed, and toiseverthese articles from the body of the members, the saws 54 are caused to operate subsequent to which they are projected to a position at which they will engage the underside of the members '40 adjacent the outer ends of the same, thus severing thoseportions of the members beyond the point at which they engage with the same, or in other words, adjacent the base of the tree portions.

Thus'all of the objects of this invention have been accomplished and it will be understood that numerous modifications of structure might readily be resorted to without in the least departing from. the scope of my claims, which are I l 1.
